- einer äußeren Führungshülse, die eine Öffnung aufweist und
- einer rotierbar innerhalb der Öffnung der äußeren Führungshülse angeordneten inneren Aufnahmehülse mit einer Ausnehmung zur Aufnahme eines Befestigungsmittels, wobei
- eine Rotationsachse der inneren Aufnahmehülse in der äußeren Führungshülse und eine Mittelachse der Ausnehmung in der inneren Aufnahmehülse zur Aufnahme des Befestigungsmittels um eine Exzentrizität voneinander beabstandet sind, wobei
- zwischen der äußeren Führungshülse (2) und der inneren Aufnahmehülse (4) eine Vorrichtung zur kraft- und/oder formschlüssigen Lagesicherung einer eingestellten Position der Aufnahmehülse (4) relativ zur Führungshülse (2) vorgesehen ist.
- an outer guide sleeve having an opening and
- a rotatably disposed within the opening of the outer guide sleeve inner receiving sleeve having a recess for receiving a fastening means, wherein
- a rotation axis of the inner receiving sleeve in the outer guide sleeve and a central axis of the recess in the inner receiving sleeve for receiving the fastening means are spaced apart by an eccentricity, wherein
- between the outer guide sleeve (2) and the inner receiving sleeve (4) is provided a device for non-positive and / or positive position securing a set position of the receiving sleeve (4) relative to the guide sleeve (2).
Bei dem Aufbau komplexer Mechanismen aus zahlreichen Bauelementen kommt es aufgrund von Bautoleranzen typischerweise zu einem unerwünschten, aber unvermeidbaren Spiel zwischen den Bauelementen, was insbesondere bei Getrieben und anderen beweglichen Mechanismen unerwünscht ist, da dies zu einer erhöhten Abnutzung, ungenauem Betrieb und unerwünschter Geräuschentwicklung führt.In constructing complex mechanisms of numerous components, construction tolerances typically result in undesirable but unavoidable backlash between the components, which is undesirable particularly in gearboxes and other movable mechanisms, as this leads to increased wear, inaccurate operation, and unwanted noise.
Mittels einer Lagerungseinheit der eingangs genannten Art, die eine Exzentrizität aufweist, kann ein solches Spiel nach Montage aller Bauelemente durch Verdrehen der inneren Aufnahmehülse in Bezug zur äußeren Führungshülse behoben werden. Nach dem Einstellen müssen dann die innere Aufnahmehülse und die äußere Führungshülse in Bezug zueinander fixiert werden, um eine weitere, unerwünschte Verstellung zu verhindern.By means of a bearing unit of the type mentioned, which has an eccentricity, such a game after mounting all components can be corrected by rotating the inner receiving sleeve with respect to the outer guide sleeve. After adjustment then the inner receiving sleeve and the outer guide sleeve must be fixed in relation to each other to prevent further, undesirable adjustment.
Zu diesem Zweck sind meist zusätzliche Befestigungsmittel zwischen der inneren Aufnahmehülse und der äußeren Führungshülse vorgesehen. Die Befestigung erfolgt dabei entweder stoffschlüssig, d.h. durch irreversibles Verbinden beider Hülsen, beispielsweise mittels eine Klebstoffes oder durch Verschweißen bzw. Verlöten beider Bauteile oder mittels mechanischer Lösungen zur irreversiblen Fixierung beider Hülsen in Bezug zueinander, bei denen ein weiteres Verstellen beispielsweise durch eine Deformation von Teilen der Hülsen verhindert wird. All diese Methoden haben zum Nachteil, dass bei einer irreversiblen Fixierung kein späteres Nachstellen eines erneut aufgetretenen Spiels mehr möglich ist.For this purpose, usually additional fastening means between the inner receiving sleeve and the outer guide sleeve are provided. The attachment takes place either cohesively, i. by irreversible connection of both sleeves, for example by means of an adhesive or by welding or soldering of both components or by mechanical solutions for irreversible fixation of both sleeves in relation to each other, in which further adjustment is prevented for example by a deformation of parts of the sleeves. All these methods have the disadvantage that in an irreversible fixation no later readjustment of a re-occurred game is no longer possible.
Zusätzlich sind aus dem Stand der Technik hoch komplexe, reversible Mechanismen zur Fixierung beider Hülsen im Bezug zueinander bekannt, die aber den essentiellen Nachteil einer kostenintensiven Herstellung und eines zeitaufwändigen Einbaus und komplizierten Gebrauchs haben.In addition, from the prior art highly complex, reversible mechanisms for fixing both sleeves in relation to each other are known, but have the essential disadvantage of costly production and time-consuming installation and complicated use.
Ein weiterer Nachteil aller Lagerungsvorrichtungen des Stands der Technik besteht darin, dass das bei der Verstellung angewandte maximale Drehmoment sehr genau beachtet werden muss, um den Mechanismus, dessen Spiel mittels der verstellbaren Lagerungsvorrichtung eingestellt wird, nicht zu beschädigen. Daher sind dazu spezielle und somit teure Werkzeuge notwendig, wobei die Benutzung solcher Werkzeuge die Verstellung zusätzlich verkompliziert.Another disadvantage of all prior art storage devices is that the maximum torque applied during the adjustment must be very carefully considered in order not to damage the mechanism whose play is adjusted by means of the adjustable storage device. Therefore, special and thus expensive tools are necessary, the use of such tools further complicates the adjustment.
Der Erfindung liegt die Aufgabe zugrunde, eine Lagerungseinheit bereit zu stellen, mittels der die Position der Lagerung eines Befestigungsmittels in einfacher Weise und reproduzierbar angepasst werden kann, und die aus nur wenigen Bauteilen gebildet ist, so dass eine einfache und kostengünstige Montage möglich ist.The invention has for its object to provide a storage unit, by means of which the position of the mounting of a fastener can be easily and reproducibly adjusted, and which is formed from only a few components, so that a simple and inexpensive installation is possible.

Die erfindungsgemäße Lagerungseinheit umfasst eine äußere Führungshülse, die eine Öffnung aufweist und eine rotierbar innerhalb der Öffnung der äußeren Führungshülse angeordnete inneren Aufnahmehülse mit einer Ausnehmung zur Aufnahme eines Befestigungsmittels. Dabei sind eine Rotationsachse der inneren Aufnahmehülse in der äußeren Führungshülse und eine Mittelachse der Ausnehmung in der inneren Aufnahmehülse zur Aufnahme des Befestigungsmittels um eine Exzentrizität voneinander beabstandet. Zwischen der äußeren Führungshülse und der inneren Aufnahmehülse ist zusätzlich eine Vorrichtung zur kraft- und/oder formschlüssigen Lagesicherung einer eingestellten Position der Aufnahmehülse relativ zur Führungshülse angeordnet, um eine ungewollte Rotation der inneren Aufnahmehülse in der äußeren Führungshülse zu verhindern.The storage unit according to the invention comprises an outer guide sleeve which has an opening and a rotatable within the opening of the outer guide sleeve arranged inner receiving sleeve having a recess for receiving a fastening means. In this case, an axis of rotation of the inner receiving sleeve in the outer guide sleeve and a central axis of the recess in the inner receiving sleeve for receiving the fastening means are spaced apart by an eccentricity. Between the outer guide sleeve and the inner receiving sleeve, a device for non-positive and / or positive position securing a set position of the receiving sleeve is additionally arranged relative to the guide sleeve to prevent unwanted rotation of the inner receiving sleeve in the outer guide sleeve.
Aufgrund der Exzentrizität beider Rotationsachsen ist es in besonders einfacher Weise möglich, durch Rotation der Aufnahmehülse in der Führungshülse die Lage eines in der Ausnehmung der Aufnahmehülse angebrachten Befestigungsmittels relativ zur Führungshülse zu variieren. Der einfache Aufbau der Lagerungseinheit aus zwei Bauelementen stellt dabei eine einfache und kostengünstige Herstellung und Montage sicher. Aufgrund dieser Vorteile ist es beispielsweise in besonders einfacher Weise möglich, eine Zahnstange relativ zu einem Ritzel in einem Fahrzeugsitz, insbesondere eines Höheneinstellers eines Kraftfahrzeugsitzes, kostengünstig in Serie herzustellen und wiederholbar präzise auszurichten.Due to the eccentricity of the two axes of rotation, it is possible in a particularly simple manner to vary by rotation of the receiving sleeve in the guide sleeve, the position of a mounted in the recess of the receiving sleeve fastener relative to the guide sleeve. The simple construction of the storage unit of two components ensures a simple and cost-effective production and assembly. Because of these advantages, it is possible, for example, in a particularly simple manner, a rack relative to a pinion in a vehicle seat, in particular a height adjuster of a motor vehicle seat, inexpensive to manufacture in series and align repeatable precise.
Grundsätzlich können die äußere Führungshülse und die innere Aufnahmehülse eine beliebige Form aufweisen und aus einem beliebigen Material gebildet sein. Bevorzugt sind sie aus einem Material mit einer hohen Festigkeit und einem geringen Gewicht, beispielsweise einem Leichtmetall, Aluminium, einem Kunststoff oder einem Verbundwerkstoff gebildet, wodurch das Gesamtgewicht der Lagerungsvorrichtung in vorteilhafter Weise gering gehalten werden kann.Basically, the outer guide sleeve and the inner receiving sleeve may have any shape and be formed of any material. Preferably, they are formed of a material having a high strength and a light weight, for example, a light metal, aluminum, a plastic or a composite material, whereby the total weight of the storage device can advantageously be kept low.
Die äußere Führungshülse und/oder die innere Aufnahmehülse können dabei aus einem einzigen Bauteil oder mehreren beliebig miteinander verbundenen Bauteilen bestehen, wobei die äußere Führungshülse und/oder die innere Aufnahmehülse bevorzugt aus einem einzigen Bauteil besteht, wodurch in vorteilhafter Weise eine kostengünstige und einfache Herstellung und Montage möglich sind.The outer guide sleeve and / or the inner receiving sleeve can consist of a single component or more arbitrarily interconnected components, wherein the outer guide sleeve and / or the inner receiving sleeve preferably consists of a single component, thereby advantageously a cost-effective and simple production and Assembly are possible.
Auch ist es denkbar, dass die äußere Führungshülse nicht nur die innere Aufnahmehülse aufnimmt, sondern daneben weitere Funktionen erfüllt. Ebenso kann auch die innere Aufnahmehülse eine über die Aufnahme eines Befestigungsmittels und Rotierbarkeit innerhalb der Öffnung der äußeren Führungshülse hinausgehende Funktion erfüllen.It is also conceivable that the outer guide sleeve not only the inner receiving sleeve receives, but next fulfilled additional functions. Likewise, the inner receiving sleeve can fulfill a function beyond the reception of a fastening means and rotatability within the opening of the outer guide sleeve function.
Die äußere Führungshülse weist eine Öffnung auf, die bevorzugt im Wesentlichen rund ist, so dass die darin angeordnete innere Aufnahmehülse in der Öffnung drehbar ist. Besonders bevorzugt ist dabei die Öffnung zu wenigstens einer Fläche der äußeren Führungshülse orthogonal angeordnet und ganz besonders bevorzugt befindet sich die Öffnung orthogonal zu zwei parallelen Außenflächen der äußeren Führungshülse, so dass die Öffnung eine zylindrische Form aufweist. Weiterhin durchdringt die Öffnung bevorzugt die äußere Führungshülse dabei vollständig. Grundsätzlich kann das Verhältnis des Durchmessers der Öffnung zur Dicke der äußeren Führungshülse entlang der Öffnung beliebig gewählt sein, bevorzugt ist dieses Verhältnis größer 1, besonders bevorzugt größer 2.The outer guide sleeve has an opening, which is preferably substantially round, so that the inner receiving sleeve disposed therein is rotatable in the opening. Particularly preferably, the opening is arranged orthogonal to at least one surface of the outer guide sleeve and most preferably, the opening is orthogonal to two parallel outer surfaces of the outer guide sleeve, so that the opening has a cylindrical shape. Furthermore, the opening preferably penetrates the outer guide sleeve completely. In principle, the ratio of the diameter of the opening to the thickness of the outer guide sleeve along the opening can be chosen as desired, this ratio is preferably greater than 1, particularly preferably greater than 2.
Die innere Aufnahmehülse weist zumindest in einem Abschnitt der Außenfläche eine der Öffnung in der äußeren Führungshülse angepasste Form auf. Bevorzugt handelt es sich dabei um eine zylindrische Form, die einen geringeren Radius als die Öffnung der äußeren Führungshülse aufweist und die somit in dieser Öffnung angeordnet werden kann. Besonders bevorzugt ist der zylindrische Abschnitt im Wesentlichen genauso lang wie die Öffnung in der äußeren Führungshülse tief ist.The inner receiving sleeve has at least in a portion of the outer surface adapted to the opening in the outer guide sleeve shape. Preferably, this is a cylindrical shape having a smaller radius than the opening of the outer guide sleeve and thus can be arranged in this opening. More preferably, the cylindrical portion is substantially as long as the opening in the outer guide sleeve is deep.
Die innere Aufnahmehülse weist eine Ausnehmung auf, die bevorzugt die innere Aufnahmehülse vollständig durchdringt. Der Durchmesser der Ausnehmung der inneren Aufnahmehülse ist dabei bevorzugt kleiner als der Durchmesser des zylindrischen Abschnitts. Grundsätzlich ist allerdings auch denkbar, dass die Ausnehmung die innere Aufnahmehülse nicht vollständig durchdringt und dabei der Durchmesser der Ausnehmung größer ist als der Durchmesser des zylindrischen Abschnitts. Auch gleiche Durchmesser sind möglich.The inner receiving sleeve has a recess, which preferably completely penetrates the inner receiving sleeve. The diameter of the recess of the inner receiving sleeve is preferably smaller than the diameter of the cylindrical portion. In principle, however, it is also conceivable that the recess does not completely penetrate the inner receiving sleeve and that the diameter of the recess is larger than the diameter of the cylindrical portion. Same diameters are possible.
Die Rotationsachse der inneren Aufnahmehülse in der äußeren Führungshülse ist definiert als die Achse, die durch den Mittelpunkt der Öffnung der äußeren Führungshülse und orthogonal zu einer Stirnfläche der Öffnung verläuft, wobei die innere Aufnahmehülse in der äußeren Führungshülse um die Rotationsachse drehbar ist. Bevorzugt verläuft die Rotationsachse dabei entlang einer Normalen einer im Wesentlichen kreisrunden Stirnfläche des zylindrischen Abschnitts der inneren Aufnahmehülse und zeitgleich durch den Mittelpunkt dieser Stirnfläche.The axis of rotation of the inner receiving sleeve in the outer guide sleeve is defined as the axis passing through the center of the opening of the outer guide sleeve and orthogonal to an end face of the opening, the inner receiving sleeve in the outer guide sleeve is rotatable about the axis of rotation. Preferably, the axis of rotation runs along a normal of a substantially circular end face of the cylindrical portion of the inner receiving sleeve and at the same time through the center of this end face.
Die Mittelachse der Ausnehmung in der inneren Aufnahmehülse ist definiert als die Achse, die durch den Mittelpunkt der Ausnehmung und entlang einer Normalen der bevorzugt im Wesentlichen kreisrunden Fläche der Ausnehmung verläuft.
Dabei verlaufen die Rotationsachse und die Mittelachse parallel zueinander, wobei beide Achsen voneinander beabstandet sind. Der Abstand beider Achsen ist definiert als die Exzentrizität der beiden Achsen bzw. der inneren Aufnahmehülse.
Die Exzentrizität kann dabei beliebig groß sein, bevorzugt ist sie allerdings kleiner als der halbe Radius der Ausnehmung, besonders bevorzugt kleiner als ein Viertel des Radius der Ausnehmung. Die Größe der Exzentrizität ist dabei bestimmend für die maximale Verstellbarkeit des innerhalb der Ausnehmung der inneren Aufnahmehülse angeordneten Befestigungsmittels in Bezug zu der äußeren Führungshülse bzw. einem Bauelement, an dem diese angeordnet ist.The central axis of the recess in the inner receiving sleeve is defined as the axis which passes through the center of the recess and along a normal of the preferably substantially circular surface of the recess.
In this case, the rotation axis and the center axis are parallel to each other, wherein both axes are spaced from each other. The distance between the two axes is defined as the eccentricity of the two axes or the inner receiving sleeve.
The eccentricity can be arbitrarily large, but it is preferably less than half the radius of the recess, more preferably less than a quarter of the radius of the recess. The size of the eccentricity is determining for the maximum adjustability of the arranged within the recess of the inner receiving sleeve fastener with respect to the outer guide sleeve or a component to which it is arranged.
Bei dem Befestigungsmittel kann es sich um eine beliebige Vorrichtung zur Befestigung handeln, beispielsweise um eine Mutter, einen Stift, einen Splint, eine Achse, eine Gewindestange, eine Schraube oder einen Bolzen.The attachment means may be any attachment device, such as a nut, pin, cotter pin, shaft, threaded rod, screw or bolt.
Gemäß der Erfindung ist die Vorrichtung zur kraft- und/oder formschlüssigen Lagesicherung eine Vorrichtung zur Verrastung der inneren Aufnahmehülse in Bezug zur äußeren Führungshülse, die bevorzugt an den Kontaktflächen der inneren Aufnahmehülse und/oder äußeren Führungshülse im Bereich der Öffnung angeordnet ist. Erfindungsgemäß ist die Vorrichtung zur Verrastung durch eine Verzahnung der Kontaktfläche der inneren Aufnahmehülse und/oder äußeren Führungshülse gebildet, wodurch in einfacher Weise eine selbsthemmende Wirkung der Vorrichtung zur Verrastung erreicht wird. Ganz besonders bevorzugt ist die Verzahnung derart ausgestaltet, dass die Drehbewegung in eine Vorzugsrichtung erleichtert ist. Dazu ist eine verrundete Verzahnung vorgesehen, wobei zur Ausbildung einer Vorzugsrichtung der Radius der Verrundung wenigstens einer der Verzahnungen entlang einer Drehrichtung deutlich größer ist als in der anderen Drehrichtung. Denkbar ist auch die Anordnung einer verrundeten Kerbverzahnung auf wenigstens einem der verzahnten Bauelemente. Erfindungsgemäß ist die Verzahnung aus einem elastischen Material gebildet und deformiert während der Verdrehung der inneren Aufnahmehülse in Bezug zur äußeren Führungshülse elastisch, wobei bevorzugt ein benötigtes Moment zur Überwindung des Zahneingriffs deutlich über einem Reibmoment zwischen der inneren Aufnahmehülse und der äußeren Führungshülsen während des Betriebs liegt. Hierdurch wird vorteilhaft im Betrieb der Lagerungseinheit eine Selbsthemmung der Verstellbarkeit der inneren Aufnahmehülse in der äußeren Führungshülse gewährleistet, während die Ausrichtung der inneren Aufnahmehülse in der äußeren Führungshülse in besonders einfacher Weise und äußerst effizient erfolgen kann. Erfindungsgemäß sind die innere Aufnahmehülse und/oder die äußere Führungshülse wenigstens teilweise, bevorzugt vollständig aus Kunststoff gebildet, wobei es sich besonders bevorzugt um einem elastischen Kunststoff mit hoher Festigkeit handelt, beispielsweise Polyethylen, Polypropylen oder Polyacetat.

According to the invention, the locking device is formed by a toothing of the contact surface of the inner receiving sleeve and / or outer guide sleeve, whereby a self-locking effect of the device for locking is achieved in a simple manner. Most preferably, the toothing is configured such that the rotational movement is facilitated in a preferred direction. For this purpose, a rounded toothing is provided, wherein for forming a preferred direction of the radius of the rounding of at least one of the teeth along a direction of rotation is significantly greater than in the other direction of rotation. Also conceivable is the arrangement of a rounded serration on at least one of the toothed components. According to the invention, the toothing is formed of an elastic material and deforms elastically during the rotation of the inner receiving sleeve with respect to the outer guide sleeve, wherein preferably a torque required to overcome the meshing engagement is well above a friction torque between the inner receiving sleeve and the outer guide sleeves during operation. This advantageously ensures a self-locking of the adjustability of the inner receiving sleeve in the outer guide sleeve during operation of the bearing unit, while the alignment of the inner receiving sleeve in the outer guide sleeve can be done in a particularly simple manner and extremely efficient. According to the invention, the inner receiving sleeve and / or the outer guide sleeve are at least partially, preferably completely formed from plastic, which is particularly preferably an elastic plastic with high strength, for example polyethylene, polypropylene or polyacetate.

Nach einer bevorzugten Weiterbildung der Erfindung weist die innere Aufnahmehülse einen Flansch auf, der bevorzugt im montierten Zustand der inneren Aufnahmehülse wenigstens mit einer Fläche gegen die äußere Führungshülse abgestützt ist, wobei die Fläche bevorzugt orthogonal zur der Rotationsachse der inneren Aufnahmehülse angeordnet ist und ganz besonders bevorzugt im Bereich der Öffnung der äußeren Führungshülse vollständig flach verläuft. Hierdurch kann in einfacher Weise eine feste Positionierung der inneren Aufnahmehülse in der Öffnung der äußeren Führungshülse erreicht und eine einfacher und kostengünstige Montage der Lagerungsvorrichtung gewährleistet werden.According to a preferred embodiment of the invention, the inner receiving sleeve has a flange which is preferably supported in the assembled state of the inner receiving sleeve at least with a surface against the outer guide sleeve, wherein the surface is preferably arranged orthogonal to the axis of rotation of the inner receiving sleeve and very particularly preferred runs completely flat in the region of the opening of the outer guide sleeve. In this way, a fixed positioning of the inner receiving sleeve in the opening of the outer guide sleeve can be achieved in a simple manner and a simple and cost-effective installation of the storage device can be ensured.
Nach einer besonders bevorzugten Weiterbildung der Erfindung erstreckt sich jeweils ein Teil der innere Aufnahmehülse beidseitig über den Flansch hinaus, wobei bevorzugt der eine dieser beiden Teile bis zu dem Flansch in die Öffnung der äußeren Führungshülse geschoben ist und besonders bevorzugt von dieser vollständig aufgenommen wird, ohne dabei aus der zur anderen, dem Flansch abgewandten Seite der Öffnung heraus zu ragen.According to a particularly preferred embodiment of the invention, each part of the inner receiving sleeve extends beyond the flange on both sides, wherein preferably one of these two parts is pushed up to the flange in the opening of the outer guide sleeve and is particularly preferably completely absorbed by this, without to protrude from the other side, the flange facing away from the opening out.
Gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung ist der Flansch wenigstens in einem Bereich als ein Betätigungsbereich ausgeformt, der bevorzugt mittels eines Werkzeugs, insbesondere eines Sechskantschlüssels greifbar ist, womit die gesamte innere Aufnahmehülse in der äußeren Führungshülse gedreht werden kann, um die Position des in der Ausnehmung der inneren Aufnahmehülse angeordneten Befestigungsmittels in einfacher Weise relativ zur äußeren Führungshülse zu variieren.According to a particularly advantageous embodiment of the invention, the flange is formed at least in one area as an operating area, which is preferably accessible by means of a tool, in particular a hexagonal wrench, whereby the entire inner receiving sleeve in the outer guide sleeve can be rotated to vary the position of the arranged in the recess of the inner receiving sleeve fastener in a simple manner relative to the outer guide sleeve.
Gemäß einer ganz besonders bevorzugten Ausgestaltung der Erfindung ist der Betätigungsbereich derart gebildet, dass ab einem definierten, auf den Betätigungsbereich wirkenden Drehmoment dieser elastisch deformiert, wodurch ein Werkzeug, mit dem die innere Aufnahmehülse gedreht wird, an dem Betätigungsbereich definiert abrutscht und somit reproduzierbar eine Verstellung der inneren Aufnahmehülse in besonders einfacher Weise mit im Wesentlichen gleichbleibendem Drehmoment erreicht wird. Dies ist insbesondere bei einer in Serienfertigung hergestellten Vorrichtung vorteilhaft, da es dabei zu jeweils einem leicht abweichenden Spiel der Baukomponenten kommt und durch die elastische Deformation des Betätigungsbereichs das aufbringbare Drehmoment wiederholbar begrenzt wird, wodurch eine gleichbleibende Einstellung innerhalb einer Bauserie in besonders einfacher Weise gewährleistet ist.According to a particularly preferred embodiment of the invention, the actuating portion is formed such that from a defined, acting on the operating torque of this elastically deformed, whereby a tool with which the inner receiving sleeve is rotated, slips defined on the operating range and thus reproducibly an adjustment the inner receiving sleeve is achieved in a particularly simple manner with substantially constant torque. This is particularly advantageous in a device produced in mass production, since it comes to a slightly different play of the components and is repeatedly limited by the elastic deformation of the operating range, the applicable torque, whereby a constant adjustment within a series of construction is ensured in a particularly simple manner ,
Gemäß einer vorteilhaften Weiterbildung der Erfindung weist die äußere Führungshülse einen Bereich zum Kontakt mit oder zur Befestigung an einem weiteren Bauelement auf, der bevorzugt als eine ebene Fläche ausgebildet ist.According to an advantageous development of the invention, the outer guide sleeve has a region for contact with or for attachment to a further component, which is preferably designed as a flat surface.

Die äußere Führungshülse 2 weist dabei eine kreisrunde Öffnung 3 in einer ebenen Stirnfläche 17 sowie einen orthogonal zur Stirnfläche 17 angeordneten, flachen Bereich zur Befestigung 10 an einem weiteren Bauteil auf. Die gewölbte seitliche Wandung der Öffnung 3 bildet eine äußere Kontaktfläche 6, die mit einer Verzahnung 8 versehen ist (vgl.
Die innere Aufnahmehülse 4 besitzt einen Abschnitt mit einer außenliegenden, zylinderförmigen Kontaktfläche 7, deren Radius geringfügig kleiner ist als der Radius der Öffnung 3 der äußeren Führungshülse 2. Die Außenseite dies zylinderförmigen Abschnitts 13 der inneren Aufnahmehülse 4 ist ebenfalls mit einer Verzahnung 9 auf der Oberfläche versehen (vgl.
Angrenzend an den zylinderförmigen Abschnitt 13 der inneren Aufnahmehülse 4 ist ein Flansch 11 angeordnet, dessen äußerste Kante als Betätigungsbereich 12 derart ausgebildet ist, dass dieser mittels eines Sechskantschlüssels gegriffen werden kann (
Im montierten Zustand der Lagerungsvorrichtung ist der zylinderförmige Abschnitt 13 der inneren Aufnahmehülse 4 bis zum Kontakt des Flansches 11 mit der Stirnfläche 17 der äußeren Führungshülse 2 in die Öffnung 3 der äußeren Führungshülse 2 geschoben. Dabei kann mittels eines Sechskantschlüssels die innere Aufnahmehülse 4 an dem Betätigungsbereich 12 des Flansches 11 gegriffen und gedreht werden, wobei die äußere Verzahnung 8 auf der Kontaktfläche 6 der Öffnung 3 der äußeren Führungshülse 2 und die innere Verzahnung 9 auf der Kontaktfläche 7 des zylinderförmigen Abschnitts 13 der inneren Aufnahmehülse 4 elastisch deformiert, so dass bei einem definierten Drehmoment sich die Position der inneren Aufnahmehülse 4 in der Öffnung 2 der äußeren Führungshülse 2 um eine Zahnposition der im Kontakt stehenden Verzahnungen 8,9 verändert.In the assembled state of the storage device of the
Die Drehung der inneren Aufnahmehülse 4 innerhalb der Öffnung 3 der äußeren Führungshülse 2 erfolgt um eine Rotationsachse 14, die durch den Mittelpunkt des zylinderförmigen Abschnitts 13 der inneren Führungshülse 4 sowie auch durch den Mittelpunkt der Öffnung 3 der äußeren Führungshülse 2 verläuft. Diese Rotationsachse 14 ist um eine Exzentrizität 16 von einer Mittelachse 15 der Ausnehmung 5 der inneren Aufnahmehülse 4 beabstandet, wobei die Mittelachse 15 durch den Mittelpunkt der Ausnehmung 5 und zeitgleich parallel zur Rotationsachse 14 der inneren Aufnahmehülse 4 verläuft.The rotation of the
Durch diese Anordnung wird durch eine Drehung der inneren Aufnahmehülse 4 ein in der Ausnehmung 5 angeordneter Bolzen in Bezug zu der äußeren Führungshülse 2 nicht nur rotiert, sondern auch entlang einer kreisförmigen Bahn in seiner Position verändert. Auf diese Weise ist es beispielsweise möglich, eine Zahnstange relativ zu einem Ritzel in einem Fahrzeugsitz, insbesondere eines Höheneinstellers eines Kraftfahrzeugsitzes, präzise auszurichten.As a result of this arrangement, rotation of the
Um eine übermäßige Belastung der Lagerungsvorrichtung 1 und damit verbundener Bauteile beim Verdrehen der inneren Aufnahmehülse 4 innerhalb der Öffnung 3 der äußeren Führungshülse 2 zu vermeiden, sind das Material und die Form des Betätigungsbereichs 12 des Flansches 11 an der inneren Aufnahmehülse 4 derart gewählt, dass ein daran angreifendes Werkzeug bei Überschreitung eines vordefinierten Drehmomentes aufgrund einer elastischen Deformation des Materials den Halt verliert. Hierdurch wird eine Wiederholbarkeit der Einstellung über das aufbringbare Drehmoment, was aufgrund der Verformung des Betätigungsbereichs 12 begrenzt ist, insbesondere bei einem seriengefertigten Bauelement umfassend die Lagerungseinheit 1 gewährleistet.In order to avoid excessive loading of the
